>Description:
Command:
ifconfig xl0 inet 192.168.2.4 netmask 255.255.255.0 alias
Shows the following output:
ifconfig: ioctl (SIOCAIFADDR): File exists

rc.conf parameter

ifconfig_xl0_alias0="inet 192.168.2.4 netmask 255.255.255.0"

has no effect as well.
In the same time, IP aliases are working well on FreeBSD 4.4-RELEASE.

Could you help me to set up additional IP addresses for my network interface? 
>How-To-Repeat:
No special actions should be taken; the system has been installed by default with GENERIC kernel.
The problem appears when I tried all available network interfaces:
xl0  3Com 905B-TX adapter;
ep0  3Com 509 ISA adapter;
fxp0 Intel 82559 PRO/100 adapter.
